Restek’s new Raptor™ SPP LC column line began with the innovative Biphenyl phase, and it has now grown to include a new Restek® phase: the ARC-18.

Designed and intended specifically for use on LC-MS/MS systems, the Raptor™ARC-18 column offers a well-balanced retention profile without the drawbacks of using an ordinary C18 in the harsh, acidic mobile phases needed for mass spectrom¬etry (MS). Even after extended use in these low-pH (≤ 2.0) conditions, the sterically protected ARC-18 offers consistent retention, peak shape, and response for charged bases, neutral acids, small polar compounds, and more. For the rapid analysis of large, multiclass assays by LC-MS/MS, the Raptor™ ARC-18 truly is ahead of the curve.

About Raptor™ SPP LC Columns: Superficially porous particles (commonly referred to as SPP or “core-shell” particles) changed the world of LC by dramatically boosting column efficiency and reducing analysis times, but they were only the beginning. With Raptor™ LC columns, Restek chemists have combined the speed of SPP with the resolution of highly selective USLC® technology. This new species of chromatographic column allows you to more easily achieve peak separation and faster analysis times without expensive UHPLC instrumentation. Raptor™ LC columns provide the practicing analyst with the most powerful tools avail¬able for fast, efficient method development and increased sample throughput. And because they are from Restek, Raptor™ LC columns are backed by manufacturing and quality systems you trust along with internationally renowned Plus 1 service.
